Littlehales, George W. Altitude, azimuth, and geographical position; comprising graphical tables for finding the altitude and azimuth, the position-line, and the variations of the compass; and for identifying observed celestial bodies, and finding the course and distance in great circle sailing. *$25.

“An attempt to bring within the grasp of the ordinary navigating officer those more recondite methods of his art, which, for their complete understanding, involve a considerable knowledge of mathematics and nautical astronomy. Great circle sailing, astronomical determinations of the compass error, Sumner’s method for finding the position of a ship, all involve the solution of spherical triangles, and it is the function of the present work to substitute for the conventional logarithmic solution of these triangles the use of certain diagrams here published in great detail.”—Engin. N.
“The labour undergone in the preparation can only be appreciated by those used to such matters; and the result in the saving of labour and time to practical navigators, by a graphical process easy to understand and follow must lay them under a deep debt of gratitude to the author. We feel sure that his method will be extensively adopted.”
